Urbanization was one of the most important social changes of the Industrial Revolution, and its effects can still be seen in the crowded cities of the modern world. Urbanization is the process by which large numbers of people move from the countryside into towns and cities, causing those centers to grow rapidly in size and population. During the Industrial Revolution, this movement happened on a scale never seen before, as families left rural farms and villages to find work in the new factories, mills, and mines of industrial towns. In just a single century, societies that had been mostly rural for thousands of years were transformed into societies where most people lived in cities.
More specifically, urbanization refers to the growth in the share of a population that lives in urban areas rather than in the countryside. It involves both the physical growth of cities, as new streets, factories, and housing spread outward, and the shift of people away from farming and toward industrial work. In the context of the Industrial Revolution, urbanization was closely tied to the rise of the factory system, which pulled workers into a small number of crowded industrial centers.
What Was the Industrial Revolution?
The Industrial Revolution was a period of major industrialization that took place from the late 1700s until the early 1900s. During this time, economies were transformed by the introduction of machinery and by innovations such as the steam engine, which shifted societies based on agriculture toward societies based on industrial production. It is considered one of the most significant events in all of world history because of the profound impact it had on the modern world.
The Industrial Revolution began first in Britain in the 1700s, but it soon spread to the rest of Europe and North America. Before it started, most goods were produced on a very small scale, often inside people’s homes, in a system that is known as the cottage industry. The revolution replaced this small-scale home production with large factories, which brought thousands of workers together under one roof and greatly increased the amount of goods that could be produced.
As stated above, the changes of the Industrial Revolution reached far beyond the factory floor. In fact, the revolution reshaped where people lived, how they worked, and how their families survived from day to day. Urbanization was one of the clearest and most lasting of these changes, and it grew directly out of the demand for factory workers.
What Caused Urbanization During the Industrial Revolution?
The main cause of urbanization was the rise of the factory system. As factories were built in and around towns, they created a huge demand for workers, and people migrated from the rural countryside to the city centers in search of jobs. This mass movement of people is often described as rural-to-urban migration, and it caused industrial towns to grow at a remarkable speed.
Another key cause was the Agricultural Revolution, which took place alongside the Industrial Revolution. New farming methods increased the amount of food that could be produced, which in turn allowed the population to grow. At the same time, changes such as the Enclosure Movement forced many farmers and their families off the land they had worked for generations.
For instance, the Enclosure Movement fenced off land that had once been shared and open, leaving many rural families without a way to farm and support themselves. With few options left in the countryside, these families moved to more populated centers in search of work. In reality, this combination of a growing population and a lack of rural work pushed enormous numbers of people toward the factories of the industrial towns.
How Fast Did Industrial Cities Grow?
The growth of industrial cities during this period was extraordinary. In Britain, which was the world’s first industrial society, cities expanded so quickly that they became the first truly urban society in history. The Industrial Revolution turned a largely rural nation into a largely urban one within the span of about a century.
To understand the scale of this change, it helps to look at the numbers. In 1801, only about one-fifth of the population of the United Kingdom lived in towns and cities of 10,000 or more people. By 1851, that share had risen to two-fifths, and if smaller towns are included, more than half the population could be counted as urban. By 1901, roughly three-quarters of the population lived in urban areas.
Individual cities showed just how fast this growth could be. For instance, the population of London doubled from about 1 million to 2.3 million people between 1801 and 1851. Manchester became so important as a center of the cotton and textile trade that it stood as an international hub of industry, drawing workers from across the countryside into its mills.
Living Conditions in Industrial Cities
Because cities grew so quickly, they were often built without proper planning, and this created serious problems for the people who lived in them. The living conditions in industrial towns were miserable and were marked by overcrowding, poor sanitation, the spread of disease, and pollution. Families frequently lived in cramped, poorly constructed housing with little fresh air.
A common feature of industrial cities was the construction of inexpensive and poorly built row housing meant for working-class people. Wealthy factory owners and entrepreneurs built these homes for their workers, but they also used them as a way to make more profit. The homes were often called back-to-back terraces because they were built side by side and connected to one another, with only the front of each home left open.
More specifically, these homes were made with the cheapest materials available and lacked basic features such as windows and proper ventilation. Most were built without running water or sanitation, which meant that many people were unable to bathe and suffered from very poor hygiene. In many cases, several families were forced to share a single room, which made conditions even more crowded.
How Did Urbanization Affect Public Health?
The lack of sanitation in industrial towns had a devastating effect on public health. Since most homes did not have running water or a way to remove waste, people often dumped their filth and waste directly into the streets. This made the streets of industrial towns incredibly dirty and allowed communicable diseases to spread easily from one person to another.
Much of this waste was also emptied into local rivers, which left them horribly polluted. Because drinking water frequently came into contact with sewage, deadly diseases such as cholera, typhoid, and typhus spread quickly through crowded neighborhoods. Cholera was especially feared, and industrial Britain suffered major cholera outbreaks in the years around 1831, 1848, 1854, and 1867.
The human cost of these conditions was terrible. In fact, infant mortality was extremely high in industrial cities, and in some towns during the 1840s, a large share of children died before reaching the age of five. Over time, disasters like these pushed governments to act, and reforms such as new sewer systems and clean water supplies slowly began to improve life in the cities.
Significance of Urbanization in the Industrial Revolution
Urbanization was one of the key features of the Industrial Revolution, and its significance reaches all the way to the present day. It permanently changed the way human beings lived by shifting the center of daily life from the farm to the city. The crowded, fast-growing cities of the industrial age became the model for the modern urban world.
The problems created by rapid urbanization also had lasting effects on how societies were governed. As people saw the suffering caused by overcrowding, disease, and pollution, reformers pushed for laws to improve housing, sanitation, and public health. In reality, many of the ideas behind modern city planning, clean water systems, and public health rules can be traced back to the effort to fix the problems of industrial cities.
Finally, the trend toward urban living that began during the Industrial Revolution never stopped. For instance, in 2009 it was reported that, for the first time in history, more people around the world lived in urban areas than in rural areas. This shows that the great movement of people into cities, which began in the industrial towns of Britain, continues to shape the world today.
Frequently Asked Questions
What does urbanization mean in the Industrial Revolution?
Urbanization means the movement of large numbers of people from the countryside into towns and cities, causing those cities to grow quickly. During the Industrial Revolution, this happened because new factories created a huge demand for workers, and people left rural areas to fill those jobs. The result was that societies which had been mostly rural became mostly urban in only a few generations.
Why did people move to cities during the Industrial Revolution?
People moved to cities mainly to find work in the new factories, mills, and mines. Many rural families had also lost their land because of changes like the Enclosure Movement, which left them with few ways to earn a living in the countryside. The promise of steady wages in industrial towns drew millions of people away from farming and into city life.
Which cities grew the most during the Industrial Revolution?
In Britain, London and Manchester were among the cities that grew the most. London’s population doubled in the first half of the 1800s, while Manchester became a world center of the cotton and textile industry. Later, as industrialization spread, cities in Europe and North America experienced the same kind of rapid growth.
What were the problems caused by urbanization?
The main problems were overcrowding, poor sanitation, disease, and pollution. Because cities grew faster than housing and services could keep up, workers often lived in cramped homes without clean water or proper waste removal. These conditions allowed deadly diseases such as cholera and typhoid to spread quickly and led to very high death rates.
How did urbanization change over time?
Over time, the terrible conditions in industrial cities led governments to pass reforms that improved housing, water supplies, and sanitation. Engineers built new sewer systems and clean water networks that slowly made cities healthier places to live. The overall movement of people into cities, however, continued long after the Industrial Revolution and remains a defining feature of the modern world.
